Like reference characters refer to like parts in the different figuresof the drawing.

The record book to which my invention can be applied may be ofwell-known construction including spaced covers 1 and 2 'connected by aflexible back 3 so that the covers may be opened and having ring orprongdevices, indicated at i, with which the loose leaves of the book areadapted to be connected, the leaves at one edge having openings to passsaid rings 4, the rings being of a type capable of being opened to passthrough the openings in the edges of the leaves or inserts.

A series of leaves or inserts, indicated at 5, is adapted to be bound inthe book between the covers and said leaves are in width but a fractionof the distance between the upper and lower edges of the record bookcovers. The leaves overlap each other for a considerable portion oftheir width but each leaf or insert at its lower edge on one face of theseries and at its upper edge on the other face of the same series has anexposed portion on which indicia of the written record on the leaf mayappear, to indicatewhat the leaf refers to, and all the indicia on all.the leaves will be presented for inspection when the record book isopened above a series of the leaves or inserts.

It is evident that as thus assembled there will be, at both the upperand lower ends of the record book, in a series of leaves 5, aprogressivereduction in thickness, as indicated at 6, byreason of thenumber of thicknesses of leaves decreasing at both the upper and thelower edges of the book. The series of leaves are separated by divisionsheet 7, located between each series and between the outside series andthe covers 1 and 2. With a plurality of the series of leaves between thecovers 1 and 2 of the book there is a tapering of the thickness of thematerial between the covers nearly to a point at both the upper edges ofthe book as shown in Fig. 1 and with a consequent bending'of some of thedivision sheets 7.

In my invention the division sheets indicated at 7 are replaced by otherdivision sheets made in accordance with my invention. Such divisionsheets indicated at 8 in Figs.

2, 3 and 4:, comprises a plane sheet having a plurality of lengths ofpaper 9 cemented at one side and at one end of the sheet, and a similarseries of lengths of paper 10 eemented to each other and to the oppositeside of the sheet at the other end. These lengths of paper 9 and 10 areof varying widths, the widest being in direct contact with the sheet 8and cemented thereto along a narrow strip adjacent to the openings shownand the next widest similarly cemented to the widest and so on, wherebythe lengths of paper 9 and 10 when attached to the division sheetpresent a stepped construction fully appearing in Figs. 3 and at. Theamount that the innermost widest length 9 of paper is wider than the onenext adjacent is equal to the amount that any of the record sheets 5extends beyond the sheet next above, that is, the amount of the exposedupper edge portion of therecord sheet in contact with lengths of paper9, and the exposed lower edge portion of the record sheet in contact.with lengths of paper 10.

\Vhen the division sheets 8 are located in the book between adjacentseries of record sheets 5, the built-up stepped parts 9 and 10compensate for and practically fill the space left vacant in theordinary construction as shown in Fig. 1 due to the running out of thematerial of the, record sheets 5 at the upper and lower edges of thebook. Above the lower cover 1 of the book a division sheet 8a is usedwhich has only the stepped series of lengths of paper 9a secured at itslower end and upper side; and under the upper cover 2, a sheet 8?) isused which is equipped only with the step series of lengths of paper 10aat the upper end and under side of the sheet.

It is, of course, to be understood that the number of lengths of varyingwidths of paper 9 and 10 used will be dependent upon the size of therecord sheets 5, and different weights or thickness of record sheets 5will be compensated with paper 9 and 10 of the same weight or thickness.But in any case therecan be constructed division sheets of the characterdescribed which will fully compensate for the reduction. in thickness ina series of overlapping record sheets at the upper and lower edges ofthe series and eliminate theundesirable narrowing of the body of therecord book between the covers at its upper and lower edges.

It should be noted thatthe engagement of the edges of the record sheetswith the exposed edges of the parts 9 and 10 will serve to "hold therecord sheets against angular movement on the connecting rings l." Theconnection of therecord sheets 5 with the rings 4 is a loose one andsuch sheets are likely to move around and drop down to a position out ofdirect alignment with the uppe'rian'd lower edges of the covers, whereascementing and joining together of the parts at one end alone isdesirable in order to re-' tain the flexibility of the paper Which islost to a very large degree bycementing severalthicknesses of papertogether completely. This cementing of the'parts 11 at one end isindicated at 13 in Fig. 7 Also the staggered side of the filler thusmade may be covered bya covering sheet 12 extending beyond the edges ofthe thicknesses of paper as shown, and the ends of the parts 11 have thesame openings that the division sheets and the record sheets have forpassing the securing rings 4 therethrough. Fillers of this kind may beused next todivision sheets like the sheets 7 in Fig. 1 at either sidethereof, as an equivalent for the parts 9 and 10 connected directly to adivision sheet.

The construction while simple is very prac tical and serviceable and hasso proved in practice. The invention is defined in the appended claimsand is to be considered comprehensive of all forms ofstructure comingwithin their scope.

I claim l 1. A filler for the purposes describ prising, a, plurality oflengths of thin sheet material of progressively decreasing Widthslocated one over the other with the widest of said lengths of materialat the bottom and the narrowest at the top, one of the edges of all ofsaid lengths of material together at one end.

2. A construction containing the elements in combination defined inclaim 1, combined with an additional length of thin sheet materiallocated over the upper side of the fillerand cemented at one endthereto, said additional length of materialbeing wider than thelowermost widest length offirstmentionedlengths of material andextendingbeyond the same.
